Question about cost to rewire a car

Gonna use the Ron Francis XP-777 Mopar express series kit and add relays so that the electric water pump, fan and duel pump are all on relays.
Little over 600 bucks for the kit with the extra relays but suits getting marker lights and other odds and ends on the new system.
Do it once, do it right.
Once i have this done and get my engine bay painted i will have the car exactly how i want it.
